ATTACHMENT FOB. PAPER-MAKING MACHINES.

leaves the press rolls of the paper machine and before it enters thedrying machine; the device being ot' special advantage as used in themanufacture of tissue, and all other papers which are liable to clingto, rather than part freely from, the press rolls while in a damp state,thus destroying the paper and requiring a longer time-in the course ofmanufacture.

The ob ect of the invention is to produce a device of this class thatshall he durable and eflicient, and be readily adaptable to paper-makingmachines of the usual type, enabling the machines to be run at a greaterspeed and the use of a cheaper quality of paper stock.

Another object of the invention is to provide a device that shall smoothand stretch and combination of parts as will hereinafter be fullydescribed and claimed in the annexed specification and illustrated inthe accompanying drawings which form a partof this application, and inwhich like figures oi reference refer to corresponding parts in all ofthe views but it fully understood that while we have here described ourinvention as shown, that we do not confine om'selves to the exactdesign, as slight changes may be made in the construction andarrangement of the several parts with out departing from the spirit ofthe invention.

I Specification of Letters Eatent. 'Pg mgnted Feb, 11, 1913,.Application filed November 15, 1911. Serial No. 661,193.

In the drawings :Figure -l, is a partial side elevation of the dischargeend 01 a paper-making machine and the receiving end of a diner, showingour device attached thereto. Fig. 2, is a top plan view of: the

same.

Referring to the dra vings-:-The side frames of'a paper-making machineare ind? cated,by the numeral 1, and within which are counted the pressrolls 2, and 3, and the roller I 3, supporting the pulp conveysr belt l.

\Vithout the employment of our device the pressed pulp or damp paper 5,is carried directly to the receiving roll a, ct a drying machine 7, andas it does not receive any support or guidance, other than itself, ithas a tendency to adhere to the roller 2, which causes it to break. Toprevent this, We have secured to the side frames 1, of the papermachine, the supportilg brackets 53, to which are secured in anadjustable manner thelearings 9, within which is mounted a rocker-shaft-10, to which is secured a scraper or doctor blade 1]., by the clamos11;,

pressure controlled by a counter-weighs "13, slidably and adjustablymounted on an arm 26, secured to sald shaft 10, and by this device thepulp or damp paper 5, is prevented from adhering to and being carriedaround by said roll 2. I

To guide, support and stretch the paper, taking out all crimp caused bythe doctorblade 11, the rollers 14, and 15, are provided. The roller 14,is rotatably mounted in the bearings 16, secured to the brackets of thepaper machine, and the roller 15, is rotatably mounted in bearings 27, scure to the drier; the pulp or damp paper L passing over these rolls l4,and 15, to th drier. T he roll 14, is driven by a pulley l secured uponthe projecting a id or shaft l8. and a belt '19. from a pulley 20,secured upon the shaft 21, of the roller 3. The projecting end 18, ofthe roller 14 and the pr W6 claim as new and desire to secure by LettersPatent is 1. The combination with a paper-making machine provided with apress roll, cooperating with a paper drying machine provided with apaper-receiving roll, and

means for parting the damp paper from said press roll, of meansforsupporting and stretching said damp paper between the press roll of saidpaper-making machine and the receiving roll of said paper dryingmachine. 4

2. The combination with a paper-making machine provided with a pressroll, and cooperating with a paper drying machine provided with a paperrecelving roll, having means'tor parting the damp paper from said pressroll,ei'rmprising a scraper blade mounted adjacent thereto and incontact therewith, of means for supporting and stretching the travelingpaper between said rolls.

The combination with a paper-making L machine having a paper pressingroller and cooperating with a paper drying machine having a paperreceiving roller, of means for preventing the paper from adhering to andfollowing the press roller past the center, means for supporting saidpaper during its travel cdmprising a roller mounted upon said papermachine to support and carry said papei and a roller mounted on the endof the drier to support and carry said paper.

4. The combination with the paper press roll of a paper-making machineand the receiving-roll of a drying machine, of means for parting thepaper rom said press roll, means for supporting and stretching saidpaper between said rolls, comprising a pair of supporting rolls spaced.apart and'means for driving the second of said rolls at a greater speedthan the first roll to pull the paper between said rolls.

In testimony whereof we affix our signatures in presence of twowitnesses.
